Sodium carbonate, Na₂CO₃ a.k.a. kansui is an alkaline salt that is essential for making ramen noodles. In Japan ramen noodles can't be called ramen noodles if the noodles don't contain a form of alkaline solution. Kansui consists of several alkaline salts: sodium carbonate, potassium carbonate and sodium biphosphate, that, in general, enhance water absorption and increases the noodle’s extensibility, responsible for their characteristic abilities making it so different than brittle wheat pasta for instance. When the right ratio of alkaline salts is applied, it either gives the noodles a chewy and elastic texture and yellow color - in case of sodium carbonate - or a stiff and firm texture - in case of potassium carbonate. So kansui needs to be used in specific ratios such as:
- 4:6 sodium to potassium - i.e. refined shio)
- 2:8 sodium to potassium - i.e. Hakata-style ramen
- 6:4 sodium to potassium - i.e. chuka soba)
In can also be used in different quantities (in ratio to totall weight of dough), depending on the type of noodle, but most times doesn't exceed 1 to 2 grams per 100 grams of flour. The kansui solution is dissolved in nerimizu or the liquid made by mixing salt, kansui and vitamin B2, before adding it to the dry mix (high protein flour, eggwhite powder and wheat gluten). So kansui is a must having in your kitchen when making authentic ramen noodles. Sodium carbonate comes in packages of 500 gram.

SAFETY WARNING: However keep ik mind that potassium carbonate is a chemical known as a caustic. So don't exceed 1 or 2 grams total on 100 grams of flour.
